Serial No. 663,156.

T 0 all whom it may concern Be it known that 1, DAVID S. KENNEDY, acitizen of the United States, of the borough of Brooklyn, county ofKings, and State of New York, have invented a new and useful Improvementin Line-Casting Machines, of which the following is a specification.

This invention has reference to Mergenthaler machines and kindred typecasting and composing machines, in which matrices or type representingthe various characters, stored in a magazine, are released one at a timethrough the action of escapement devices controlled by finger keys.

My invention relates to mechanism in which a single finger key isarranged to control the means for releasing matrices from two channelsalternatelyboth channels carrying ordinarily matrices for the samecharacter. I

The object of the invention is to permit the use of a large number ofmatrices of those few characters which are required with greatfrequency.

with the finger key of an automatic vibratory dog or latch which servesto communicate motion from the key to two reeds alternately, these reedsacting either directly or through intermediate mechanism on therespective escapement devices.

I have shown my invention as applied to mechanism of the well knownMergenthaler type now in commercial use. With the ex ception of theparts herein shown the machine may be in all respects of any ordinary orsuitable construction.

Referring to the drawings: Figure 1 is an outline perspective viewshowing the mouth of the magazine, two escapements, and their 7controlling devices, in accordance with my invention. Fig. 2 is a rearelevation showing the dog or latch in the opposite position from thatshown in Fig. 1. Fig. 3 is a vertical section on the line 33 of Fig. 2.Figs. 1 and 2 are views showing the different positions the dog assumesin the course of its action.

In the drawings, A. represents an inclined longitudinally channeledmagazine in which the matrices, B, B, are stored.

C, C represent the escapements controlling the delivery of the matrices,each consisting of a centrally pivoted lever carrying at opposite endstwo upright pawls or dogs, which are projected alternately into themagazine-the lower pawl standing normally in an elevated position, toretain the foremost matrix.

D, D are vertically guided reeds acting at their upper ends on therespective escapements.

E, E are vertically movable cam yokes, pivoted at one end, and actingbeneath the respective reeds D, D, to lift them.

F, F are cams mounted in the respective yokes and overlying thecontinuously rotating rolls G and G, being normally out of contacttherewith.

H, H are two dogs pivoted to the main frame and serving to hold theinner ends of the yokes normally in an elevated position,

to prevent the contact of the cams with the driving rolls.

I, I are pins by which the cams, heavier on one side of the center thanon the other, are prevented from turning downward prematurely.

J J are vertically guided" bars receiving motion from a finger key K,and serving to actuate the dogs, H, H and permit the fall of the yokesand cams, so that the latter may receive motion, one at a time, from therolls, the effect of the rotation being to lift the reeds and actuatethe escapements.

So far as described, with the exception of the connection between thefinger keys and the bars J, J, the parts may all be constructed andarranged to operate in the manner set forth in Letters Patent of theUnited tates No. 530,931.

In the mechanism as heretofore constructed there was a finger key foreach of the bars J, J; in other words, a finger key for each escapement.In carrying my invention into effect, and in order to operate twoescapements alternately from the one key, I provide the rear end of thekey with a dog or latch L. This dog is constructed with a transverseslot Z, with the two shoulders Z and Z on opposite sides, above theslot, and with the pointed lower end Z It is mount ed on a journal orpivot 70, on the rear end of the finger key, so that it may rock thereonand also shift bodily to the right and left. Beneath the finger key, onthe main frame, I secure a beveled or pointed block M, in posi- .tion toencounter the dog L when the latter descends. On the bars J and J I formthe lips j and j, to engage the dog L.

The operation of the parts is as follows: Assume the finger key to be atrest and the .dog L in its lowermost position, with its lower endresting on the left side of the i block M, as shown in Fig. 1. When thekey weight of the bar on the shoulder j, to the left of the pivot onwhich the dog is mounted, causes the dog to slide or shift laterally atits lower end toward the right, as shown in Fig. 2 so that its lower endoverlies the right side of the block M. As it completes its downwardmovement the pivot, actingin the slot, in combination with the block M,shifts the .dog bodily,.to the right, as indicated by dotted lines inFig. 2; so that when the dog is next lifted, by the second action of thefinger key, its right hand shoulder will engage under the bar J, whichwill be lifted, While the bar J remains at rest. In this manner,- by thejoint action of the shoulders,

matrices delivered alternately from two channels ofthe magazine.

While it is preferred to operate the escapement through the intermediatecams and rolls, it is to be understood that these interf mediate partsmay be omitted, and the slides J and J continued directly upward to theescapements, which latter will then receive motion directly from thefinger key.

The essence of the invention lies in a latch carried by the fingerkeyand vibrated automatically so that it may actuate the slides or reedsalternately.

While the invention is intended more par- Copies of this patent may beobtained for five cents each, by addressing 7 Washington, D. G.

ticularly for application to line casting machines, it will of course beunderstood that it .is also applicable to composing machines,

and machines for casting and composing type, type dies,etc.

Having described my invention what I claim is: I

1. In combination, two vertically arranged slides, a horizontallydisposed finger key, and an automatic dog carried by the key andcontrolled by the operation of the key so as to actuate the slidesalternately. I

2. In combination, two slides, a single finger key, an oscillating dogcarried by the key, and stationary means for reversing the position ofthe dog at each action of thekey so as to actuate the slidesalternately.

3. In combination, two slides, an actuating member, andan automatic dogcarried and controlled by said member and provided with two shoulderswhich engage the slides alternately.

4c. The two slides, a reciprocating dog, an actuating member carryingsaid dog, and

stationary cooperating means whereby the v reciprocation of the dogreverses its posit-ion periodically, so that it will actuate the twoslides one at a time.

5. In combination, the actuating member,

the dog mounted to vibrate and also shift bodily sidewise on the member,the two slides, and means to vibrate and shift the 7 dog, whereby thedog engages the slides one at a time. i

6. In combination, the two bars J and J, a reciprocable finger key, adog provided with shoulders, and mounted to move relacooperate with thedog during its reciprocation, substantially as described.

7. In combination, the barsJ andvJ, finger key K,the slotted dog carriedby the finger'key, and having a pivotal and shifting motion thereon, anda stationary member, M, to cooperate with the dog whereby the bars areactuated alternately.

In testimony whereof I hereunto set my hand this 20th day of November,1911-, in the presence of two attesting witnesses. 7
